Abstract (en)
An interfolding machine includes a first folding roll (90) with a series of the gripper assemblies and a series of tucker assemblies (20) uniformly and alternately spaced to interact with a series of gripper and tucker assemblies of an adjacent second folding roll (95). The series of alternately spaced gripper and tucker assemblies interact to grip, carry, and release a sheet of material in a manner so as to generate an interfolded stack of sheets. Each tucker assembly (20) includes an outwardly biased tucker element (125) that is operable to self-center in a slot formed in the folding roll. The tucker assembly further includes a roller (134,136) mounted by a pin (140,142) to the tucker element such that the tucker element rolls along a surface defined by the slot. Another embodiment of the tucker assembly includes a pivot spring and bumper to self-center the tucker element in the slot. <IMAGE>
